I bring here a few quotes from Brunton and Sri Aurobindo. But the basic idea was mentioned by others as these ideas apply all too well in the religious world where spiritual leaders have obvioulsy fallen into this realm of illusion.
The pathway of the mystical goal is strewn with human wreckage. Why? Several reasons would be needed to give a complete answer but one of the most important is this: Between the state of ordinary man and the state of the matured mystic there lies a perilous and deceptive psychological region which has been given various names in mystical literature. It has been called the astral plane, the intermediate zone, the hall of illusion, and so on. The early efforts of all aspirants in concentration, meditation, self-conquest, and study, bring them into this region. But once here their egoism becomes stimulated by the subtle forces they have evoked, their emotional nature becomes more sensitive and more fluid, their imaginative power becomes more active and is less restrained. The consequence of failure to negotiate these changes properly is swollen vanity, superstitious credulity, emotions run riot, and imagination gone wild...

These things, when they pour down or come in, present themselves with a great force, a vivid sense of inspiration or illumination, much sensation of light and joy, an impression of widening and power. The sadhak feels himself freed from the normal limits, projected into a wonderful new world of experience, filled and enlarged and exalted; what comes associates itself, besides, with his aspirations, ambitions, notions of spiritual fulfilment and yogic siddhi; it is represented even as itself that realisation and fulfilment. Very easily he is carried away by the splendour and the rush, and thinks that he has realised more than he has truly done, something final or at least something sovereignly true.
– Sri Aurobindo, The Riddle of the World, 35
This is in fact an intermediary state, a zone of transition between the ordinary consciousness in mind and the true yoga knowledge. One may cross without hurt through it, perceiving at once or at an early stage its real nature and refusing to be detained by its half-lights and tempting but imperfect and often mixed and misleading experiences; one may go astray in it, follow false voices and mendacious guidance, and that ends in a spiritual disaster; or one may take up one’s abode in this intermediate zone, care to go no farther and build there some half-truth which one takes for the whole truth or become the instrument of the powers of these transitional planes, - that is what happens to many sadhaks and yogis.
– Sri Aurobindo, The Riddle of the World, 36-7
